I was reading another thread earlier, and the OP noted that for the past five oil changes, a different oil was used for each change. OTOH, I've been using pretty much the same brand of oil for years. I started out with Red Line in 1984 and used it with excellent results in my two Mazdas until 1991 when I purchased a new Ranger. I met an engineer from an oil company and he suggested I try M1, and through a couple-three vehicles since then, that's what I've used.
Please understand that I'm not being judgemental, just curious. What motivates you to keep changing brands of oil for the same car over time?
